DBCO-PEG4-Butyraldehyde is a click chemistry PEG reagent containing a terminal butylraldehyde group. Butyraldehyde reacts with hydrazide to form a stable hydrazone linkage or with alkoxyamines to form a stable oxime bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research use only.

Norgen’s Legionella sp. TaqMan PCR Kit is designed for the detection of Legionella sp. specific DNA in a real-time PCR based on the use of TaqMan technology. This kit is designed for research use only and not for use in diagnostic procedures. The detection of Legionella sp. specific DNA is based on TaqMan PCR providing a simple, reliable and rapid result for the detection of Legionella sp. infection. Norgen’s Legionella sp. TaqMan PCR Kit includes a PCR control to monitor for PCR inhibition, and to validate the quality of the sample and the detection result. The Legionella sp. TaqMan PCR Kit comprises Master Mix for the target and PCR control detection, Primer & Probe Mix, as well as a positive control and a negative control (nuclease-free water) to confirm the integrity of the kit reagents.

Storage Conditions and Product Stability
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
All kit components should be stored at -20°C upon arrival. Repeated thawing and freezing (> 2 x) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.

Sample type purification kit guide
The 16S V3-V4 Library Preparation Kit for Illumina consists of the reagents and components required for library preparation of the 16S V3-V4 amplicon libraries to be used for next-generation sequencing on Illumina platforms. All molecular reagents including primers, enzyme mixes, indexes, and buffers are provided. Instructions for PCR clean up with the AMPure XP Magnetic Beads (supplied by customer) are also included for rapid purification of nucleic acid products generated at two steps of the workflow. The library prep workflow could be used for purified DNA inputs from different sources including stool, soil, water, saliva, plant, urine, skin swab, vaginal swab, cheek swab, nasal swab, plasma/serum, tongue swab, gum swab, and others.
The 16S V3-V4 Library Preparation Kit for Illumina has a streamlined procedure that reduces the handling time such that the library prep procedure can be completed in approximately 4 hours (see diagram below). Input DNA is first subjected to targeted PCR to amplify the V3-V4 region of the DNA encoding 16S rRNA. The post-PCR reaction is then cleaned up using AMPure XP beads. Dual index primers are then added using a limited-cycle PCR. The indexed amplicons flanked by 5′ and 3′ barcoded adaptors are then cleaned using AMPure XP beads. The libraries are then ready for quantification, pooling and sequencing.
| Minimum amount of starting material: | 2.5 µL of DNA (5 ng/µL) |
| Time to complete library preparation: | 4 hours |
Storage Conditions and Product Stability
Norgen’s 16S V3-V4 Library Prep Kit for Illumina is shipped as one kit box (for the 24 prep kit) or two sub-component kits (for the 96 prep kit). All kits should be stored at -20°C upon arrival.
All kit components should remain stable for at least 1 year when stored at the specified storage conditions.

Description
The PM2610/PM2611 ExcelBand™ Enhanced 3-color High Range Protein Marker is a ready to use three-color protein standard with 12 pre-stained proteins covering a wide range of molecular weights from 10 to 245 kDa in Tris-Glycine buffer (9 to 235 kDa in BisTris (MOPS) buffer and 10-235 kDa in Bis-Tris (MES) buffer). Proteins are covalently coupled with different chromophores for easy identification of bands, with two reference proteins carrying enhanced intensity corresponding to a green at 25 kDa and red at 75 kDa, respectively, as separated on SDS-PAGE (Tris-Glycine buffer). The ExcelBand™ Enhanced 3-color High Range Protein Marker is designed for monitoring protein separation during SDS-polyacrylamide gel electrophoresis, verification of Western transfer efficiency on membranes (PVDF, nylon, or nitrocellulose) and for approximating the size of proteins.
Features
Contents
Approximately 0.2~0.6 mg/ml of each protein in the buffer (20 mM Tris-phosphate (pH 7.5 at 25°C), 2 % SDS, 3.6 M Urea, and 15 % (v/v) Glycerol).
Quality Control
Under suggested conditions, the PM2610/PM2611 Enhanced 3-color High Range Protein Marker resolves 12 major bands in 15% SDS-PAGE (Tris-Glycine buffer, MOPS, and MES buffer) and after Western blotting to nitrocellulose membrane.
Storage
4°C for 3 months
-20°C for long term storage
